That view is now out of date. Plants take up intact amino acids and small peptides directly through their roots, and in many soils organic nitrogen is a significant part of what they actually use (Näsholm et al., 1998; Näsholm, Kielland \u0026amp; Ganeteg, 2009).\u003c\/p\u003e\n\u003cp\u003eThat is what this product supplies. The nitrogen here is held in amino acids and proteins, drawn from fermented plant material and concentrated into a granule. Some is taken up directly; the rest is mineralised by soil biology at a measured pace.

Speed depends on soil temperature and moisture — it is faster in warm, moist soil.\u003c\/div\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"drf-faq\"\u003e\n\u003cinput type=\"checkbox\" id=\"drf-ne-faq7\"\u003e\u003clabel class=\"drf-faq-q\" for=\"drf-ne-faq7\"\u003eWill it scorch or burn my plants?\u003c\/label\u003e\n\u003cdiv class=\"drf-faq-a\"\u003e\u003cdiv\u003eIt has a low salt index, so it is far gentler than synthetic nitrogen, but it is still a concentrated 13% feed. Keep the granules off foliage, stems and crowns, stick to the stated rates, and water in well. The main risk is over-application: too much nitrogen drives soft growth that flops and attracts aphids, and heavy doses on dry soil can scorch.\u003c\/div\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"drf-faq\"\u003e\n\u003cinput type=\"checkbox\" id=\"drf-ne-faq8\"\u003e\u003clabel class=\"drf-faq-q\" for=\"drf-ne-faq8\"\u003eCan I use it on all plants, including edibles?\u003c\/label\u003e\n\u003cdiv class=\"drf-faq-a\"\u003e\u003cdiv\u003eYes, on edibles, ornamentals and lawns. It shines on leafy and hungry crops and during early, leafy growth. Go easy on flowering and fruiting plants once they have set buds — too much nitrogen then pushes leaves at the expense of flowers and fruit, so switch to a balanced or high-potash feed at that stage.\u003c\/div\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"drf-faq\"\u003e\n\u003cinput type=\"checkbox\" id=\"drf-ne-faq9\"\u003e\u003clabel class=\"drf-faq-q\" for=\"drf-ne-faq9\"\u003eIs it safe for children, pets and wildlife?\u003c\/label\u003e\n\u003cdiv class=\"drf-faq-a\"\u003e\u003cdiv\u003eIt is a plant-based feed with a low salt content, and it has no strong smell to attract animals.

A high-nitrogen feed like this corrects it: roughly half the nitrogen is available within a fortnight for a quick green-up, with the rest released over the following weeks. Apply at the stated rate, water in, and avoid over-applying, as too much nitrogen brings its own problems.\u003c\/div\u003e\u003c\/div\u003e\n\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Dr Forest","offers":[{"title":"1.5kg","offer_id":46312501608635,"sku":null,"price":12.99,"currency_code":"GBP","in_stock":true},{"title":"4kg","offer_id":46312501641403,"sku":null,"price":26.0,"currency_code":"GBP","in_stock":true},{"title":"9kg","offer_id":46312501674171,"sku":null,"price":48.99,"currency_code":"GBP","in_stock":true},{"title":"15kg","offer_id":46312501706939,"sku":null,"price":70.0,"currency_code":"GBP","in_stock":true},{"title":"30kg","offer_id":57795182723446,"sku":null,"price":136.49,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0049\/8194\/8504\/files\/organic-nitrogen-fertiliser-two-brown-compostable-paper-bags-743.png?v=1774789092","url":"https:\/\/www.drforest.co.uk\/products\/organic-nitrogen-fertiliser","provider":"Dr Forest","version":"1.0","type":"link"}
